ALARM WATER-GAG E.

SPECIFICATION forming part of Letters Patent No. 380,881, dated April10, 1888. Application filed January 9, 1888. Serial No.260,1-16. (Nomodel.)

To all whom. it may concern. l

Be it known that we, GEORGE FIsHER and PETER RAPPOLD, citizens of theUnited States, of Toledo, in the county of Lucas and State of Ohio, haveinvented certain new and useful Improvements in an Alarm Tater-Gage; andwe do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters of reference markedthereon,which form part of this specification.

Our invention relates to an alarm water-- gage, and is designed toindicate the accumu lat-ion of water in the hold of a vessel, and alsoto sound an alarm when the water rises beyond a certain depth.

The object of the invention is to provide a gage having adj ustabilityof parts as well as a flexible portion intermediate the indicator andfloat that shall not be affected by the movement of the vessel whenrolling, and to attach to the gage an alarm that shall be caused toannounce when water shall have accumulated in the holdto any depth towhich the alarm is I arranged to operate.

The invention consists in a well extending from the bilge to the upperdeck, and within which is a hollow float, preferably of oval shape,having a threaded rod passing through its major axis, the perforationsin the float through which the rod passes being also threaded to allowthe float to be adjusted upon the rod to any desired height, the upperend of the rod being attached by means of flexible connections to arevoluble disk having a central stud, to which is connected an indicatorto mark the rise of water in the hold and an alarm mechanism caused tooperate by being tripped by a cam or projection upon the central stud.

In the drawings, Figure 1 is a Vertical cen tral section of the well,the indicator being shown in front elevation. Fig. 2 is an enlargeddetail view of the revoluble disk. Fig. 3 is an enlarged detail views,howing the tripping arrangement alarm mechanism. Fig. 4 is a plan Viewof the well on lines y 1/, Fig. 1. Fig. 5 is a detail view of the alarmmechanism.

A designates the well, )referably formed of tubular pipe B, theextension of the same consisting of a tubular pipe of smaller diameterthan well A, and secured in cap F, at the top thereof, by being threadedat the lower end and screwed into a threaded perforation in said cap.

E designates a transverse plate secured centrally of the length andwithin the well, and provided with a perforation centrally of itsdiameter through which passes rod D, having at its threaded lower end afloat, O, with a threaded perforation centrally of its axis, by whichmeans the float is adj ustabl y secured to the rod. The upper end of rodD is formed with perforations, (preferably two,) for a purposehereinafter stated. Upon the upper side of plate E are secured twogrooved pulleys, T.

G designates flexible connections,with the rod D and an alarmgagesecured at any convenient point upon the vessel. The flexibleconnection,whieh may be an ordinary cord or rope and consisting of twostrands,which are attached each at one end to the upper end of rod D bybeing passed through the perforations and secured, and are then passedunder pulleys T, the strands being separated and one passed under eachpulley, and from thence through the well and extensionpipe B, at

l which point the strands are joined to form one cord or rope, which issecured to the periphery of a revoluble disk, H, having acentral stud,I, secured to the disk in such manner as to re volve therewith, theinner end of the stud be ing journaled in the hanger or board L, towhich the alarmgage is attached, the opposite end revolving in a hearingwithin dial, N, and intermediate the two bearings having a cam orprojection, P, the portion of stud extending outwardly from the dialhaving a pointer, M, attached thereto.

- K is a coil-spring attached to studl and to hanger L.

O designates a jointed lever having a catch, Q, adapted to engage and belocked in position with a stud, Q, upon hanger L. The horizontal portion0 of jointed lever O is forked, and has pallets O engaging with ascapewheel, 0', connected by a train of gearing to an arbor havingacoiled spring woundthereon.

Since this portion of the device may be of any well-known form, itisunnecessary to illustrate the same further, it only being necessary thatthe scape-wheel 0 be connected, as by any well-known clock gearing andspring, to have a normal tendency to revolve and actuate the escapementwhen the catch Q of the lever O is released from the stud Q.

R designates a hammer connected with the train of gearing and caused tosound an alarm upon a gong, S, attached to the frame encircling thetrain of gearing.

P designates a lever fulcrnined at P and having an angled portionnormally resting against the lever O, the opposite portion restingwithin the radius of travel of the cam or projection I? of the stud Iwhen revolved.

In operation,when water accumulates in the bilge and enters the wellthrough the perforations in the bottom, the float rises correspondingly,and by the connection of the rod D with the flexible connections and tothe revoluble disk H revolves the same, causing the pointer to indicateupon the dial the depth of water in the vessel, and as the stud Icontinues to revolve with the further revolution of the disk the lever Pis moved and trips the rod 0, thereby allowing the scape-wheel torevolve, the pallets of the forked lever O determining the revolution ofthe wheel as they alternately engage and disengage with the teeth of thescape-wheel, and the hammer R is caused to sound the alarm upon the gongS.

It will be seen that our device is inexpensive, and that by the flexibleconnection of the rod with the alarm-gage the gage may be placed in anyconvenient position on the vessel without regard to its relationvertically with the well.

The float being adjustable upon the rod on ables the device to beadjusted to indicate any desired depth of water, and by varying thepoint of attachment of the cord or rope upon the disk H a furtheradjustment of the indicator and alarm may be effected.

Having described our invention, what we claim, and desire to secure byLetters Patent, 1s-- 1. In an alarm water-gage, a Well, a floatadjustably secured to a vertical rod within the well,having a flexibleconnection with an alarm and indicator, as and for the purpose setforth.

2. In an alarm water-gage, a well, a hollow float therein adjustablysecured to a vertical rod, in combination with an alarm mechanism, andropes or like connections with the rod and alarm mechanism, as and forthe purpose set forth.

3. In an alarm water-gage, a well, a float adjustably secured to a rodmoving therein and through a transverse plate secured within the well,in combination with a disk revolving with a central stud having anindicator upon one end and a tripping-lug centrally thereof adapted torelease an escapement connected with an alarm, and a flexible connectionfrom the rod to the disk, as and for the purpose set forth.

In testimony that we claim the foregoing as our own we hereby aflix oursignatures in presence of two witnesses.
